Definitions
- the present invention relates to methods, apparatus or equipment and systems for lining conduits, e.g., preferably subterranean pipelines and passageways, such as sewers, with a liner impregnated with a curable resin in order to secure the conduit against ingress or egress of liquids.
- conduits e.g., preferably subterranean pipelines and passageways, such as sewers
- U.S. Pat. No. 4,685,983 to Long, Jr. discloses a method and apparatus for installing a flexible tubular liner into a pipe, by means of pressurized air.
- the apparatus includes means for defining a pressurized region for inserting the liner into the pipe and an insertion conduit, having an entry end and exit end connected to the means defining the pressurized region.
- Means are provided on the exit end of the insertion conduit for sealing and clamping the leading end of the liner to the exit end of the insertion conduit and for creating a fluid tight seal between the liner and the insertion conduit.
- the leading end of the liner is then turned inside out for the first six inches to form a cuff which is pulled back over the outside of the insertion conduit exit end and is secured using a clamping means.
- the water valves are then opened to allow water to flow through the water pipe and to enter the top of the insertion conduit. Because the leading end of the liner is secured to the insertion conduit exit end, the water will be contained within the insertion conduit and will fill the insertion conduit.
- the water pressure within the insertion conduit builds up to a predetermined level, the water pressure causes the liner to invert and move along the pipe.
- the water continues to flow into the insertion conduit to maintain the water pressure at a level sufficient to move the liner along the pipe.
- a trailing end of the liner reaches the insertion conduit entry end, the operation is stopped and a rope is secured to the trailing end of the liner.
- the liner is cured.
- U.S. Pat. No. 6,679,293 to Driver discloses a process for lining an existing pipeline with a flexible resin impregnated cured in place liner by pulling in the liner and inflating an eversion bladder with air and curing the liner with flow-through steam without loss of pressure.
- the bladder is everted by means of pressurized air. Steam is introduced into the bladder to cure the resin, after which the bladder is removed.
- U.S. Pat. No. 6,390,795 to Waring et al. discloses an apparatus for use in installing a liner in a conduit as part of a repair procedure, wherein the apparatus includes a sealing inlet port for passage of the tubular liner into an enclosed zone where an increased fluid pressure is maintained to move the tubular liner into the conduit and to evert it as it moves along the conduit.
- the apparatus also includes a container for holding air or another fluid under pressure to act on the flexible tube.
- the sealing inlet port is provided in the container to allow the liner to enter the container in a flattened configuration without significant loss of pressure, so that the pressure of the fluid in the container can be used to evert and extend the tubular liner into the required position within a conduit.
- U.S. Pat. No. 4,752,511 to Driver discloses a method and apparatus for sealing the space between a pipe and a lining applied to the pipe's interior, wherein sealing rings are provided between the lining and the pipe to prevent fluid from passing through spaces between the pipe and the lining.
- the patent further teaches that water or other fluid is used to evert the liner into and along the interior of the pipe.
- U.S. Pat. No. 6,708,728 to Driver et al. discloses a “pull in and inflate” method for lining a pipeline with a flexible resin impregnated cured in place liner.
- Liner is pulled into a pipeline section to be relined by pulling in the liner and inflating an eversion bladder with air and curing the liner with flow-through steam introduced in the bladder. After curing is completed, the bladder is removed.
- the bladder is cuffed around the inflatable member and clamped around the outer surface of the launcher, and the pipe liner is then cuffed over the inflatable member on the outside of the bladder.
- the pipe liner is impregnated with a curable resin before being installed onto the launcher.
- the launcher is then attached to a positioning device (e.g., a rotating/lifting machine or a system of cables including pulleys and cables attached to the launcher and operated to pull and guide the launcher) for movement into position within the sewer pipe.
- the positioning device and the launcher are inserted into the main line of the sewer pipe and the launcher is positioned relative to a discrete location within the sewer pipe.
- a drawback observed in many current pipelining systems is the need to use a thermal curing resin to impregnate the tubular liner, as it is then necessary to maintain the resin at a significantly reduced temperature in order to retard or hold back the curing process until the liner is fully inserted into the intended conduit or pipeline.
- the liner is initially cooled at a centralized liner preparation facility.
- the liner has to be kept under refrigeration. In this way, the liners can be transported a substantial distance to the remote job site, hopefully without any curing of the resin during transportation.
- the same equipment can be used to impregnate and otherwise prepare liners concurrently for different jobs at widely separated job sites, however this is all extremely risky and very expensive.
- Suitable resin concentration in the impregnated liner is determined at least in part by the natural ability of the fabric material to absorb the various resin liquids used in the impregnation, which again depends on the current temperatures as the resin viscosity also changes with temperature at which the impregnation and the rate of impregnation can occur. These rates will change depending on the materials, resin (e.g., resin viscosity) and fabric (e.g., fabric density) used.
- resin e.g., resin viscosity
- fabric e.g., fabric density
- the present invention is directed, in part, to a method for inverting a tubular liner in a hollow conduit, particularly a subterranean passageway or pipeline, e.g., a sewer pipe, storm drain, and the like.
- the present invention is directed to a method for lining a hollow conduit with a resin-impregnated tubular liner and a flexible light curing activator tube, an apparatus for inverting a translucent tubular bladder in a hollow conduit while inserting the flexible light activator tube to cure the liner as it is installed.
- the present invention is directed to a method for pulling or placing a resin-impregnated tubular liner along with the flexible light activator tube and a translucent bladder together in unison as one device, for the tubular lining of a hollow conduit or a partial section of it.
- the methods are much simpler and faster than conventional methods for inverting or placing a liner in a conduit and for the curing of the resin impregnated liner, the methods and apparatus are more consistent and with less risks for use in an underground hollow conduit.
- the methods, apparatus and system of the invention allow for the liner to be curing as the inversion or installation procedure takes place.
- the methods, apparatus and systems also minimize all the known associated risks and costs by removing temperature as part of the equation in relation to heat assisted or ambient curing thermal resin mechanisms, and all of their related costs along with the risks associated in the transportation, as well as the potential time factors for the intended conduit to be closed or by-passed during the installation process and the curing stage of the resin-impregnated liner.
- the present invention provides a method for inverting a tubular liner in a hollow conduit comprising:
- the present invention provides a method of lining a hollow conduit with a tubular liner comprising:
- restricting a region of the liner between the cuff and the exposed liner thereby temporarily restricts the liner while the flexible light activator is attached to the trailing end of the liner.
- the gas is allowed to pass through into the liner, thereby causing inversion, inflation and curing of the liner while the remainder of the liner is inverted through to the end.
- the rate of curing is regulated by controlling the speed of the trailing end of the liner as its pulling the light activator through the liner inside the conduit, maintaining or establishing a pressure in an interior portion of the inverted liner such that the pressure is sufficient to keep the liner against the inside surface of the conduit.
- another step of curing the resin in the liner is introduced, as the trailing end attached to the light activator moves through the entire liner towards the end, away from the initial starting point.
- the present invention provides for a method of lining a hollow conduit with a tubular liner, for use on partial repairs or to shorter sections of conduit or for smaller diameters and short lengths of hollow conduits.
- the resin-lined tubular liner in conjunction with a translucent bladder and flexible light curing activator, can be pushed or pulled into place into the hollow conduit in its entirety, and then when in position, inflating the translucent bladder with a gas, which in turn presses the tubular liner tight against the host pipe or hollow conduit wall, before the flexible light activator device, which is central positioned within the translucent bladder and host pipe, is powered up to start the curing process.
- the present invention provides for a method of lining a hollow conduit with a tubular liner, wherein the liner is impregnated with a light-activated resin before the liner is inserted or placed within the conduit.
- the liner does not require any special cooling or large refrigerated trucks and can be installed in very hot climates without curing in advance of installation. Additionally, neither cold climates, presence of groundwater nor any extreme temperature-related issues affect the curing process.
- the gas is preferably air and the pressure of the gas is preferably from about 2 to about 30 pounds per square inch (psi) covering all diameters. Operation at atmospheric pressure requires a supplemental force to invert the liner or bladder.
- the methods of this invention may further include the step of sealing off the entrance to the device, (e.g., with a blank plate or cap and moving the inversion apparatus and another insertion device to another location to facilitate additional installations) and then proceeding with the remaining steps of the methods.
- the hollow conduit can be, for example, a water or gas pipe, a storm drain, a sewer pipe, a wastewater drain, or the like.
- an apparatus for inverting a tubular liner or bladder in a conduit comprising:
- a feeding element comprising at least one opening through which an activator is attached to a trailing end of the tubular liner or bladder before a cuff is formed from a leading end of the tubular liner or bladder;
- the activator is an electric light activator tube comprising a unit of sufficient length to improve curing time and speed with a restraining cable.
- At least one spiral centralizer is attached to the outside of the activator to ensure that the electric light activator tube is in a central position relative to the conduit to cure the tubular liner as fast as possible during installation.
- the electric light activator tube is flexible and also wrapped or encased with a passive reflecting tape to assist in dispersing UV light in all directions,
- a braking control member is also provided, for regulating the speed of the inversion, pulling the activator through the liner or bladder and can be simultaneously viewed via a camera.
- the above-described apparatus is also used to line a conduit with a tubular liner in accordance with the method of the invention.
- the present invention also comprises a combination of components with the above-described apparatus.
- the additional components include known apparatus to hold pressure and invert the liner or bladder, a viewing portal with a translucent screen and a UV protective filter built in to protect the material and yet allow an operator to observe what is contained within the device and monitor the special arrangement of the power cable that is wound or coiled on the rollers contained within the device and externally on the reel to the power restraining cable, a portable battery or power supply to provide the low power electrical supply which is connected to one end of the light activator and yet wired internally to provide power to both ends of the light activator tube, a flexible tube with a built in spiral flat portion placed at regular intervals to ensure that the flat and flexible circuit strips remain in place on the outside of the hollow tube along with the centralizers which keep the light activator tube towards the middle of the conduit even on very tight bends, while the multiple light source

- a UV activated resin-impregnated fabric tubing having had its UV protective sleeve removed during the loading of the material from its transport container and into the inversion pressure drum or apparatus, the liner or bladder is drawn through the entrance of the apparatus of this invention sufficiently to allow the first few feet of the liner or bladder to be exposed inside out from the exit point of the apparatus.
- the first few feet of the liner or bladder to be exposed inside out from the exit point of the apparatus is preferably at least about 2 feet, more preferably from about 3 feet to about 5 feet, most preferably from about 6 feet to about 15 feet, depending on the depth of the access to the pipe or conduit.
- the liner used in the present invention preferably has a thickness of at least 2 millimeters. Particularly suitable thicknesses range from about 2 millimeters up to about 18 millimeters.
- the diameter of the liner is at least 2 inches, with particularly suitable diameters ranging from about 3 inches to, e.g., 24 inches. Larger sizes can be accommodated by wiring more activators together and by providing more battery power
- the fabric forming the lining may be formed from at least one layer of resin absorbent material, such as felt or glass fiber or a combination of both.
- the resin impregnating the fabric is preferably a non VOC synthetic light activated resin, which means that it will cure with the emissions of a UV light source within a few minutes, even under water and without any environmental issues or strong odors.
- references also teach that woven or non-woven glass material can be used in addition to, or as a substitute for, these other fibers.
- the resinous impregnation liquid introduced into the fabric layers can be any number of light activated compositions.
- the resinous impregnation liquid becomes set or hardened by a UV light at a specific light range to activate the catalyst and provide a solid matrix around the fibers.
- the suitable compositions include a light-react-able agent.
- Such examples include ultraviolet curing unsaturated polyester or vinyl-ester or any non-VOC light activated resins, as disclosed in U.S. Pat. No. 6,170,531 (incorporated by reference herein), e.g., vinyl ester.
- the method and apparatus of this invention can be used to line a conduit (e.g., passageway or pipeline) in a vertical or horizontal position and of various shapes and dimensions regardless of disposition of the conduit to be repaired or lined.
- a conduit e.g., passageway or pipeline
- suitable conduits to be lined according to the present invention include those having a diameter of at least 2 inches, preferably from about 3 to 24 inches, and those having a length of at least 30 feet, preferably from about 30 feet to about 400 feet.
- the present invention is not restricted due to the dimensions of the conduit.
- the conduit to be lined preferably extends between two access locations.
- the reusable translucent bladder can be used for pipes with only one access position, as the bladder will go further than the liner end, ensuring the downstream tubular liner is expanded and cured as the bladder moves through and out of the liner end.
- the exit and entry point or just the entry point can be cut out allowing for the activator to be retrieved or pulled back through the pipe when only one access is available, the bladder and the activator is retrieved with a minimal internal pressure of 1 psi to assist in the de-inversion process as its pulled back inside itself and out of the pipe to the cuff.
- FIG. 1 shows a damaged conduit to be repaired or lined by the methods and devices of the present invention.
- FIG. 2 A describes an exemplary stage 1 situation, where conduit 10 to be lined (e.g., a sewer pipe) has a first access opening in the form of manhole chamber 10 A or cleanout, a second access opening in the form of manhole chamber 10 B, a first vertical channel, and a second vertical channel. It is to be understood that combinations of vertical channels to conduits of various geometries and diameters can also be lined using the methods, apparatus and system of this invention.
- conduit 10 to be lined e.g., a sewer pipe
- Feeding element 4 is a conventional feeding member for receiving and feeding a resin-impregnated fabric tubular liner 3 or bladder into manhole 10 A and eventually conduit 10 , through entry apparatus 1 .
- Entry apparatus 1 is located downstream of feeding element 4 and is adapted to fixedly secure an opening 1 A of cuff 3 A formed from a leading end of liner tube 3 or bladder, with clamping member 5 located downstream of cuff 3 A and a gas-inlet connector 6 located upstream at feeding element 4 and, also, light activator unit element 2 .
- a UV light protective sleeve 4 A is shown, extending from feeding element 4 to entry apparatus 1 .
- feeding element 4 comprises portal 8 for viewing and transferring spent liner post-use.
- Entry apparatus 1 may include a supporting frame to sit on or near manhole 10 A or attached directly onto any liner feeding element 4 .
- entry apparatus 1 can be located directly at the bottom of any vertical chamber or clean out within manhole 10 A.
- the system of this invention includes an entry apparatus 1 in combination with light activator unit element 2 or feeding element 4 as a combination of both chambers if size or volume is not an issue such as for smaller diameter installations.
- Light activator unit element 2 which comprises a long flexible tube encompassing a plurality of LED lights that are pre-set to a specific wavelength in order to activate the resin impregnated fabric liner as its being installed.
- This lightweight hollow flexible tube of lights also has the ability to expand under pressure of an internal gas thereby allowing the tube the possibility of expanding and changing its shape when inside the liner or bladder and therefore bringing the light arrays closer to the inside wall surface to increase curing speeds.
- Use of a passive reflecting tape also helps to mirror the light available from the source and reflect its emissions both outwardly and longitudinally inside the pipe or conduit.
- conduit 10 is reached via a cleanout or manhole 10 A, most of which are vertical shafts.
- Liner tube 3 is attached to feeding element 4 in preparation for installation within conduit 10 .
- liner tube 3 is formed of a resin absorbent fabric or a dry bladder inflation tube and has a length that is equal to or greater than the distance between manholes 10 A and 10 B. Liner can be installed in increments from about 10 to about 500 feet, depending upon conduit dimensions, logistics and physical and weight demands.
- a leading end of liner tube 3 is turned inside out for the first few feet to form cuff 3 A over opening 1 A of entry apparatus 1 or light activator unit element 2 or feeding element 4 , which is then turned back over opening 1 A and secured by a clamp to form cuff 3 A.
- Entry apparatus 1 , light activator unit element 2 and feeding element 4 have openings by which liner tube 3 is first fed through to the exit point where the opening is used to form cuff 3 A and secured or clamped onto entry apparatus 1 at opening 1 A, or on the exit points at light activator unit element 2 and feeding element 4 .
- Gas-inlet connector 6 is used upstream of cuff 3 A and opening 1 A to entry apparatus 1 , and is normally located on light activator unit element 2 and feeding element 4 to transmit air or gas from compressor 7 into liner tube 3 or bladder contained inside a preferred vessel, while feeding the remainder of liner tube 3 through cuff 3 A at opening 1 A, with gas, which is preferably air or steam, being introduced from a gas hose via gas inlet connector 6 , through feeding element 4 and into a space on entry apparatus 1 , finally delivered through liner tube 3 or bladder.
- gas which is preferably air or steam
- the gas is fed under pressure (e.g., from about 0 to about 30 psig) and, for a 24′′ diameter conduit, this would typically require gas at 4-8 psig. While an 8′′ diameter conduit requires gas at 6-12 psi, a 4′′ diameter conduit may require gas up to 20 psi due to bends and restrictions.
- cap 1 B As air is exhausted out from the feeding element 4 to atmosphere, cap 1 B is removed and the trailing liner tube 3 or bladder end is located and secured to activator assembly 2 A inside light activator unit element 2 and through the exposed cap 1 B.
- Light activator unit element 2 is then attached to entry apparatus 1 and optionally feeding element 4 can be removed and entry apparatus 1 is closed or capped at the location where liner tube 3 previously entered ( FIG. 2 D ).
- Powered light tube 2 B is activated at a time after air pressure is re-established via the other gas inlet connector 6 on light activator unit element 2 .
- Clamping member 5 is now removed and, optionally, feeding element 4 , with its tube connector and protective sleeve 4 A to entry apparatus 1 may be removed to be re-loaded with another UV resin impregnated fabric liner tube or bladder for another installation elsewhere.
- the activator assembly 2 A can be fully positioned via the inversion technique or by pulling the combined activator and translucent bladder into position, and then inflating and powering up the powered light tube 2 B to activate the curing process.
- Another option is to fully invert activator assembly 2 A to the furthest point first, then setting the cure timing by the rate or speed of retrieval to cure liner tube 3 as necessary, all the way back to the entry point of the conduit or pipe but now in a reverse direction.
- powered light tube 2 B can be turned off and the unit retrieved from this position internally by reversing direction. If used in conjunction with a bladder or removable coating, the pressure is reduced to around 1 psig in order to assist this process and activator assembly 2 A is restored into the light activator unit element 2 or other type of vessel. If activator assembly 2 A was used without a bladder, then liner tube 3 is cut open at the entrance of 10 B and the trailing end of the tubular liner can be disconnected from the activator tube, thereby allowing activator assembly 2 A to be withdrawn manually, in reverse, and stored back inside light activator unit element 2 , feeding element 4 , or other container.
- entry apparatus 1 can also be removed and any excess liner cured in the vertical sections of 10 A and/or 10 B can also be cut away, leaving the shaft clear for flow to enter.
- the leading and trailing ends of the cured liner are sealed to the inside walls of the conduit so as to prevent seepage or leakage of water or other fluid between the liner and conduit ( FIG. 2 F ).
- the apparatus of the present invention has been described with regard to a specific embodiment.
- the concept present is in essence a simplification of known processes, in particular those directed to fluid (e.g., water) processes.
- the present design encapsulates gas to lay liner in a conduit or pipeline while at the same time allowing the light activator to start the curing process as the tail or trailing end of the tubular liner travels the length of the intended installation.
- Material to the design is the inlet ports made in a stationary portion of the apparatus to allow the liner to be fed through and then cuffed at the exit point below the opening through which liner is fed, and if necessary another port to allow for the activator to enter the apparatus which can then be pulled through the tubular liner cuff by the trailing end of the tubular liner using the inversion process and without losing pressure.
- the various designs of the light activator in that the long continuous and flexible printed circuitry of a stringed arrangement of specific and multiple UV LED components which are now mounted on the flat portion of a specially designed round flexible hollow tube by a spiral or longitudinal configuration on the outside surface and yet inside a water tight translucent sleeve or tubular liner ( FIG. 5 ).
- the flexible tube within an additional translucent and flexible bladder encapsulating the light activator tube may also be pressurized to inwardly expand the circuitry or deflect the flexible tube spirally to allow for more components to be attached circumferentially and in length, thereby putting the light emissions closer towards the inside diameter of a host pipe or conduit intended for lining and thereby speeding the curing process for larger diameter pipelines or conduits.
- FIG. 6 the design for a micro unit of a very small diameter 1 inch and a short length of up to 12 inches has also been developed primarily for the residential and commercial plumbing markets to use within very tight access pipes ( FIG. 6 ).
- the flexibility of the tube in FIG. 6 is shown, with its translucent bladder 62 , multiple LED lights 66 and centralizers 68 , as expanded under gas pressure on the inside of a small diameter pipe or conduit bend.
- this flexible tube embodiment enables the pressing of the UV resin saturated tubular liner 64 tightly against the host pipe 60 or conduit for repair.
- Such a device can be negotiated through a 2 inch “P” trap to form a partial repair of approximately 4 to 6 inches in length to repair these pipes without excavation within buildings and basements in similarity to Example I.
- the design for the optics on each LED is through an entire 360 degrees from its axis or radial position and each led as a minimum backup led to one side or the other on the flexible circuit strip and then spread lengthwise and in a two way continuous power circuit (power is supplied to both ends of the activator tube) on lengths normally at a minimum of 5 feet for partial repairs, and a minimum of 50 feet, preferably a 100 feet for bigger diameter pipes.
- the overpopulation of LED lights has been designed into the system so that if 1 or 2 LED lights fail for any reason the liner will still cure with just one or more remaining LED light, in addition the optional use of the reflecting tape wrapped around the flexible tube, more than doubles the intensity of the available light emissions within an enclosed pipe or conduit.
- FIG. 7 provides for an alternative embodiment of the devices of the present invention. As shown in FIG. 7 , a combination pressure and power inversion vessel is provided for tubular liner combined with the device of FIG. 5 and FIG. 6 .
- FIG. 9 describes a device for use in a small diameter pipe, showing an inflated translucent packer.
- FIGS. 10 and 11 show the wiring connections within the tubing for use in small diameter pipe applications.
- each of the methods used a lining apparatus with variations and portions of the scope of the present invention.
- the pipeline was temporarily removed from service and plugged or capped or (i.e., bypassed) by plugging the pipeline one section upstream of the work area and pumping all flows overland to one section downstream of the work area.
- the pipe to be lined was cleaned prior to installation of the liner.
- the most recent example and use of the apparatus and method of the invention occurred at a private residence in Phoenix Ariz. where the climatic conditions precluded the use of a thermal cure process.
- the contractor a large private plumbing company had entered into a contract to repair approximately 24 feet of old 3 inch cast iron sewer pipe that had failed in several locations along the bottom of the pipe, allowing for raw sewer to flow underneath the house foundations and when the flows backed up other services had to be called in to clean the inside of the home in question.
- the contractor had chosen a spray type of process initially to fix the problems encountered however during the descaling and additional prep-work needed to help restore the old cast iron pipe, further damage ensued causing more holes to form only this time their positions were closer to the top of the pipe or at the 12 o'clock position.
- the protective sleeve encasing the raw materials for which we had previously saturated a UV resin was removed, prior to using, as the tube was cut to the required length needed.
- the protective sleeve was resealed for the remaining rolls of resin saturated material, the wet material was placed around the outside of the device and rolled it into as tight a position.
- the device was then inserted into a flexible UV resistant tube and taken to the pit to be pushed into the pipe while at the same time removing the protective tube, once in the pipe the device was pushed very easily up to the required position navigating a few bends along the way.
- the air supply which feeds through the push/power hose and special connectors, was turned on and set at 12 psi. In a few seconds the bladder on the device had expanded, thereby pushing the resin liner tight to the host pipe and covering the damaged area.
- the low power supply from the battery unit was engaged and current was transmitted inside the same single push/power hose, which in turn powered the UV LED circuit inside the device.
- the liner had cured to form a new section of pipe albeit a partial length remotely placed underground and beneath the home.
- the power was turned off at this time and the air supply was extinguished and the connection to the small compressor opened to atmosphere allowing air previously trapped in the bladder to escape.
- the bladder was free from its expanded state and the device removed from the new pipe section.
- the video inspection camera was again deployed to verify the repair was successful and that the broken section had been now covered by the structural repair cast in place.
- Another example of the method and a part of the device of the invention occurred at a location underneath a major highway within San Diego County. This involved a major problem associated with a small, 10 inch diameter storm drain of approximately 120 feet in length that ran under a very busy intersection.
- the traffic diversionary problems encountered with this location and multiple lanes with heavy traffic flows required an alternative pipe rehabilitation method, as this had to be completed on site and as fast as possible and in high elevated temperatures.
- the methods and devices described supra were utilized to solve this problem, starting late at night, which meant the UV resin liner could be removed without canopies or UV protective sheeting.
- the tubular liner was loaded into the device as described within this invention and some of its methods as shown in FIGS. 2 A- 2 F .
- the tubular liner was attached to the power cable and inverted through to the other catch basin located in the median of the freeway.
- the apparatus was inside the liner and, after 10 more minutes, the speed of inversion was calculated and set to move forward at approximately 12 feet per minute.
- Another example of the benefits of the methods and devices of the present invention occurred at a canyon location.
- a number of storm drains had been designated for repair using the standard cured-in-place-pipe (CIPP) process.
- CIPP standard cured-in-place-pipe
- the contract was severely delayed from all bidding due to local fires and eventually the project was withdrawn due to an unforeseen issue that occurred in another location within the county, whereby a previously lined storm drain that had been repaired with a CIPP liner product caught fire and, consequently, the fire spread underground up through the storm pipe and appeared in an area where the fire personnel had previously thought the home was safe from issues.
- the tubular liner was loaded onto the pipe and allowed to slide down the incline using some more lubrication and water, when the liner finally reached the downstream end which took approximately 40 minutes, a clear translucent tubular coating was inverted into the pipe, at the halfway position, the air being evacuated, a small light device was attached to the trailing end or tail of the coating the inversion began again and at 2 psi the coating had pulled the light train into place at the far end, we increased the pressure to 3 psi turned on the high power to the lights and set the retrieval speed after 10 minutes to 12 feet per minute, after retrieving the equipment the video inspection camera was deployed to see the final cured product of one continuous liner now in place in the canyon.
- the apparatus and method of this invention can be used for the installation of any cured-in-place dry liner product, once impregnated with a light sensitive resin material and delivered to site, inverted, pulled or pushed into place or into any conduit (e.g., manhole, pipeline, or vertical shaft) used to convey fluids or gas.
- any conduit e.g., manhole, pipeline, or vertical shaft
- the length of time required for installing and curing the liner will depend on a variety of factors, such as, e.g., thickness and diameter of the liner, the size and capacity of the air supply, the size and length and of the light activator.
